CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. application Ser. No. 13/405,745, now pending, filed Feb. 27, 2012, which is a continuation of U.S. application Ser. No. 12/135,574, now U.S. Pat. No. 8,136,460, filed Jun. 9, 2008, each of which are hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

The present invention is directed to a method of assembling a platform system. In particular, the present disclosure is directed to securing portable supports to frames attached to each other to form a platform system.

BACKGROUND OF THE INVENTION

Portable structures, such as stages or platforms, must be capable of being assembled and disassembled into relatively small units that can be compactly and quickly loaded onto trucks or airplanes for transport. The portable structures must be capable of being assembled and disassembled by personnel with little or no technical skill. The portable structures support a large amount of weight and are subjected to external conditions, lateral forces, loud vibrations, and substantial wear.

The portable structures are generally comprised of systems of primary and secondary supports that provide the necessary stability. These systems are often comprised of supports requiring use of tools, such as wrenches and screwdrivers, to assemble and disassemble the portable structures. Locking mechanisms for supports have been used; however, they are difficult to assemble and disassemble, subject to misalignment, require a plurality of pieces, require tools for certain adjustments, do not offer adequate stability, do not have easily replaceable parts, and do not work well in conjunction with other parts of the portable structures.

Portable structures typically used in the art include those structures that have perpendicular members extending from the platform, which are attached at the joints between decking members. The structures known in the art suffer from the drawback that they are cumbersome to assemble, subject to misalignment, causing instability in the structure, and are subject to lateral forces during use.

What is needed is a portable support and a platform system that are easily assembled and disassembled with little or no technical skill, is not substantially subject to misalignment, requires few pieces, can be substantially assembled and disassembled by hand, offers the necessary stability, has replaceable parts, and works in conjunction with the other parts of the portable structure.

SUMMARY OF THE INVENTION

In an exemplary embodiment, a method of assembling a platform system includes positioning a first frame having one or more panels, then securing a first portable support to the first frame. Then the method further includes securing a second frame to the first frame to form a first continuous platform level.

In another exemplary embodiment, a method of assembling a platform system includes positioning a plurality of frames having one or more panels to form a first continuous platform level, then securing a first portable support to at least one of the plurality of frames.

In another exemplary embodiment, a method of assembling a platform system includes forming a first continuous platform level from a plurality of frames having one or more panels, the plurality of frames including one or more receiving members. The one or more receiving members has a casing with a magnetic panel. The method includes securing portable supports to at least one of the plurality of frames, securing an additional frame having one or more panels to the portable supports, and forming a second continuous platform level from a plurality of additional frames. The adjacent receiving members are magnetically attracted.

One advantage of the present disclosure is ease of assembly and disassembly of the portable structure, reducing the possibility for assembly error in the portable structures, including in multi-level portable structures.

Another advantage of the present disclosure is the ability for individuals with little or no technical skill to assemble or disassemble the portable supports and the platform systems.

Still another advantage of the present disclosure is the substantial stability of the portable structure due to the portable support minimizing swaying, bending, and other lateral forces.

Still another advantage of the present disclosure is the relatively small number of separate parts required for use of the portable support in conjunction with the stage or platform system.

Still another advantage of the present disclosure is the ability to substantially be assembled, disassembled, and adjusted by hand.

Still another advantage of the present disclosure is that the portable support may be positioned and locked in the standing position, making the installation quicker and less burdensome on the assembler.

Still another advantage of the present disclosure is that the portable support occupies less space when it is detached from the other parts of the portable structure and, thus, diminishes the space required for transportation and storage of the portable structure using the portable support.

Other features and advantages of the present invention will be apparent from the following more detailed description of the preferred embodiment, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a platform system 101 comprising a plurality of frames 102 supported by portable supports 103, a plurality of secondary supports 105, and having a plurality of the platform panels 109 thereon. The platform panels 109 may be any type of panels 109 desirable for use with the platform system 101. In addition, panels 109 may include structural, aesthetic and/or theatrical components. For example, the platform panels 109 may include plywood, glass, metal, video components, lighting components, or any other structural, aesthetic and/or theatrical component. In addition, the frames 102 each include four receiving members 207 (see e.g., FIGS. 2 and 3). Although this embodiment is shown with frames 102 having four receiving members 207, the frames 102 may contain any number of receiving members 207 suitable for providing the support for the frame 102 and the panels 109. The embodiment shown in FIG. 1 includes a multilevel portion 110 and a single level portion 113. Each of the multilevel portion 110 and the single level portion 113 are made up of a plurality of frames 102 and panels 109. The frame 102 and panels 109 on the upper section 111 of the multilevel portion 110 are supported by a plurality of portable supports 103. The portable supports 103 extend from the lower section 112 of the multilevel portion 110. The portable supports 103 are engaged with receiving members 207 of frames 102 in the lower section 112. The portable supports 103 in the multilevel portion 110 may be friction fit and held by gravity or may be locked into place with a locking mechanism (see e.g., FIGS. 2-3). Other mechanisms may be provided to further engage the portable supports 103 to the receiving members 207. For example, grooves, features, and interlocking features may be utilized to further provide engagement between the portable support 103 and receiving member 207. The single level portion 113 includes a plurality of portable supports 103 arranged to support a single level of frames 102 and panels 109. The portable supports 103 in the single level portion 113 includes secondary supports 105 that engage the frame 102 and the secondary support structure 107. The secondary supports 105 provide increased resistance to lateral forces.

Also shown in FIG. 1 are wheels 106, which provide contact with the underlying surface of the platform system 101. Although wheels 106 are shown, other structures may be utilized including, but not limited to, rollers, fixed feet, stakes, posts, or other structures suitable for engaging the surface underlying the platform system 101. As shown in the multilevel portion 110, the wheels 106 are attached to the panels 109 and/or frame 102 to permit rolling or moving of the system 101 even after assembly. Likewise, the single level portion 113 includes footing structures 104 having wheels that are attached to the portable support 103 and permit rolling or moving of the system 101 even after assembly. In another embodiment of the disclosure the footing structures 104 can be substituted with a stabilizing device. The stabilizing device could be a device formed of a solid substance (such as concrete, plastic, or other solids that can be worked with in liquid form), a mechanical system providing shock absorption, or other systems sufficient to provide stability for the portable support 103 and/or frame 102.

The receiving members 207 arranged along the frame 102 to permit engagement with portable supports 103 from either the top surface or from the bottom to permit stacking of platform levels. That is, portable supports may be mated to the receiving member 207 from two directions, permitting the formation of multiple levels. Although the multilevel portion 110 is shown as two platform levels, any number of additional levels may be formed. In addition, the distance between platform levels may vary by providing portable supports 103 of varying lengths on each level.

In addition, the receiving members 207 permit engagement with additional staging structures desirable for staging or platform use. For example, while not so limited, as shown in FIG. 1, additional staging structures, such as stairs 115, may be engaged to the platform system 101 by insertion of a portion thereof into receiving members 207. Likewise, railings 117 may also be inserted into receiving members 207. Engagement may include any suitable engagement into receiving member 207, including, but not limited to gravity, interlocking, latching or magnetic attraction. Other staging structures may likewise be engaged to the platform system 101 by engagement with the receiving member.

The platform system 101 is easily assembled and disassembled by people of little or no technical skill. In addition, the platform system 101 provides resistance to lateral forces such as swaying or bending, the platform system 101 is not substantially subject to misalignment, the platform system 101 requires few pieces for assembly, the platform system 101 usually does not require tools for assembly or disassembly, the platform system 101 offers the necessary stability, the platform system 101 has replaceable parts, and the platform system 101 works in conjunction with the other parts of the platform system 101.

FIGS. 2 and 3 shows an embodiment of the portable support 103 engaged with a receiving member 207 according to an embodiment of the present disclosure. The portable support 103 comprises a support member 201, a locking mechanism, and a footing structure 104. The portable support 103, as shown in FIG. 2, is substantially a cylindrical support but could be of any geometry capable of supporting the frame 102 and panels 109 and loads provided thereon. The support member 201 can be made of any material but is best made of light weight and durable materials that can withstand external environmental conditions, abuse by people of little or no technical skill, and frequent transportation. The support member 201 is also best made of a material that allows for the application of a coating. This coating can be used for aesthetic purposes or to improve the ability of the support member 201 to withstand external environmental conditions. In one embodiment, a plurality of the support members 201 may be fabricated with substantially identical dimensions or marked with an identifier, such as colors, in order to allow the support members 201 to be interchanged, reducing the possibility for assembly error, especially in the assembly of the multilevel platform system 101.

The tapered portion 229 is attached to or unitarily formed at an end of the support member 201 (see e.g., FIG. 4). A footing structure 104 is attached to an end of the support member 201 opposite tapered portion 229. As shown in FIG. 2, the tapered portion 229 is engaged with receiving member 207.

One embodiment of the present disclosure, as visible in FIG. 3, includes a locking mechanism made up of a retention device 211, latching feature 203, alignment member 213, flange 215, tapered portion 229, attachment portion 231, and at least one channel 217. In the system 101 shown in FIG. 1, the locking mechanism is present in the portable supports 103 present in the single level portion 113. The locking mechanism may be positioned in multiple orientations by lining up channel 217 with the pin 219 of the receiving member 207 (see e.g. FIG. 3). Releasing mechanism 209 is arranged along a surface of the support member 201. The releasing mechanism 209 is preferably arranged as a sleeve or otherwise gripable structure that is manipulatable by hand. The releasing mechanism 209 can be operated by hand to disengage the retention device 211 and latching feature 203. The latching feature 203 is a latch, protrusion or other feature of the retention device 211 that engages one or more surfaces of the receiving member 207. The latching feature 203 extends through the tapered portion 229 and provides a surface extending therefrom that is capable of engaging a surface of the receiving member 207. As shown in FIG. 3, a series of mounting pins 243 and springs 241 are operably mounted to provide the releasably pivotable structure of the retention device 211 and the releasing mechanism 209. However, the structure of the portable support is not limited to the particular arrangement shown in FIG. 3.

The locking mechanism comprises a retention device 211 and latching feature 203, an attachment portion 231, and an alignment member 213, which further comprises at least one channel 217. The tapered portion 229 can be manually inserted into the receiving member 207. Upon inserting the tapered portion 229 into the receiving member 207, a pin 219 in the receiving member is lined up with the channel 217 in the locking mechanism to position the orientation of the locking mechanism in relation to the receiving member 207. In one embodiment the locking mechanism produces an audible clicking noise indicating that it is properly engaged to the receiving member 207. Upon fully inserting the locking mechanism into the receiving member 207, the retention device 211 engages a catch in the receiving member 207. The catch can be a hole, a slot, a groove, a notch or any other structure or feature allowing for the latching feature 203 to releasably attach lip 218 (see FIG. 5) of the receiving member 207. To disengage the locking mechanism 203, the releasing mechanism 209 is manually adjusted, resulting in the retention device 211 disengaging the latching feature 203 from the receiving member 207.

As shown in FIGS. 3-5, operation of locking mechanism is now described. A pin 245 secured in tapered portion 229 also provides a pivotable connection with retention device 211. As shown in FIG. 4, slots 247 and 249 are found in tapered portion 229. Slot 247 provides visibility of the interior of tapered portion 229 to simplify installation of pin 245 through retention device 211. Latching feature 203 extends through slot 249 to permit engagement with lip 218 (see FIG. 5). An opening 251 is formed in retaining device 211 to receive pin 243 that is secured in releasing mechanism 209. Disposed between opening 251 and latching feature 203 is a protrusion 253 that is configured to receive spring 241. Spring 241 urges locking mechanism 203 to pivot about pin 245 so that locking mechanism 203 extends through tapered portion 229. A spring 257 is disposed between a pin 255 secured in support member 201 and pin 243 secured in releasing mechanism 209. Spring 257 urges releasing mechanism 209 to move along support member 201 toward tapered portion 229.

In operation, in response to receiving member 207 being aligned and directed over and into engagement with tapered portion 229 of portable support 103, the inside surface of support cone 223 makes contact with latching feature 203. Further directed movement of receiving number 207 with respect to portable support 103 urges latching feature 203 to pivotably retract through slot 249 sufficiently to permit latching feature 203 to engage lip 218. This engagement, normally accompanied by an audible “click”, secures receiving member 207 to portable support 103.

To release receiving member 207 from portable support 103, application of a sufficient force applied to releasing mechanism 209 in a direction away from tapered portion 229 urges releasing mechanism 209 away from tapered portion 229. Pin 243 engages opening 251, compressing spring 241, and urging or actuating retention device 211 to pivotably move about pin 245 so that latching feature 203 recedes within slot 249. After latching feature 203 sufficiently recedes to disengage lip 218, receiving member 207 may be separated from portable support 103. It is to be understood that other arrangements may also be used.

In addition, the embodiment shown in FIG. 3 includes a second portable support 103′ extending from the receiving member 207. Although the embodiment shown includes a second portable support 103′, stairs 115, railings 117 or other structures may include a footing structure 104 configured to engage support cone 223 of receiving member 207 and may be engaged with the receiving member (see e.g., FIG. 1).

In one embodiment, the tapered portion 229 of portable support 103 resembles a tapered or frusto-conical geometry. The tapered portion 229 is not limited to a frusto-conical shape, and may include conical, pyramidal or other tapered geometries capable of transmitting loads at non-perpendicular angles. The tapered portion 229 provides an angle that allows resistance to lateral forces when engaged with receiving member 207. Further, the tapered portion 229 assists in alignment and ease of assembly.

The attachment portion 231 of portable support 103 may be attached to the support member 201 in any suitable manner. In one embodiment, the attachment portion 231 may be shrink fitted into a hollow support portion by heating the support member 201 to a temperature sufficient to cause the support member 201 to expand to a diameter sufficient to permit the fitting of the attachment portion 231, wherein the support member 201 is cooled to tighten the connection. A flange 215 may also be provided to permit easy attachment of the attachment portion 231 to the support member 201 and easy alignment of the attachment portion 231 to the receiving member 207 during assembly.

FIG. 2 further shows the secondary support structure 107, which is optional, comprising a set of the hook members 221 (see e.g., FIG. 12). Hook members 221 are arranged to permit at least one of the secondary supports 105 to be attached to the secondary support structure 107 allowing increased stability for the platform system 101. The engagement of the locking mechanism with the receiving member 207 includes a rotational positioning that arranges the hook members 221 in an orientation that permits placement and locking engagement of the secondary supports 105 to the portable support 103 and to the frame 102 (see e.g., FIG. 1). The secondary supports 105 may be fastened to the frame 102 in any suitable manner, including by fasteners, latches, hooks or other clipping or retaining structures.

As visible in FIG. 3, the receiving member 207 comprises support cone 223, pin 219, and casing 225. The support cone 223 is geometrically configured to allow the locking mechanism to substantially fit within the support cone 223. The pin 219 is replaceably affixed within the support cone 223 to allow at least one of the channels 217 of the locking mechanism 203 to engage the pin 219. The casing 225 includes a geometry that allows the portable support 103 to support the platform panel 109 (shown in FIG. 1), stage, or platform system 101. As shown in FIGS. 2 and 3, the casing 225 of the receiving member 207 can include at least one magnetic panel 227. The magnetic panel 227 includes a plurality of magnets 239 that are arranged to magnetically attract adjacent receiving members 207. In one embodiment the magnetic panel 227 includes six magnets 239 having alternating polarities of north and south. For example, the magnets 239 may be arranged in a north-south-north arrangement in a first set and a south-north-south arrangement in a second, adjacent set. The arrangement of alternating magnetic polarities permits the simultaneous attraction and alignment along multiple directions from receiving members 207 having magnets 239 arranged in a corresponding arrangement.

The receiving member 207 further includes a pin 219. The pin 219 is of a geometry configured to mate channel 217 of the locking mechanism 203 and provide rotational positioning of the portable support 103. Although an embodiment includes a single pin 219, multiple pins 219 can be used. The pin 219 can be of a cylindrical geometry, a cuboid geometry, or any substantially similar geometry. During the initial assembly of the receiving member 207, pin 219 may be inserted into two cavities on opposite sides of the support cone 223. Preferably, the pin 219 can be removed or replaced allowing the remaining parts of the receiving member 207 to be used if the pin 219 becomes damaged. In one preferred embodiment, the location of the pin 219 in the support cone 223 is as close to the distal end of the support cone 223 in relation to the support member 201 as possible. In another embodiment of the present disclosure, instead of having the pin 219, the receiving member 207 is configured with at least one alternate channel corresponding to the channel 217 of the alignment member 213.

The support cone 223 of the receiving member 207 is of a geometry substantially similar to the tapered portion 229 allowing the locking mechanism, including the tapered portion 229 and latching feature to fit inside of the support cone 223 and engage therewith. In one embodiment, the geometry of the support cone 223 resembles a frusto-conical geometry. The support cone 223 is made of a material that can withstand insertion of the locking mechanism 203 without the need to expend significant effort to align the locking mechanism 203 and the support cone 223. The support cone 223 preferably further includes a geometry to receive a tapered footing structure 104, stairs 115, railing 117 or other structures. The tapered surfaces of the support cone 223 may be the same or different. That is, the angle of the tapered surface may be the same or dissimilar on opposite edges of the support cone 223 (see e.g., FIG. 5). In the embodiment wherein the tapered surface are of different angles, the fitting of the components can be verified or customized to particular, predetermined components to prevent mis-assembly with insertion of incorrect components. In one embodiment, the support cone 223 is made of a material that can withstand the impact of the locking mechanism 203 being repeatedly and forcibly inserted into the support cone 223. Upon insertion of the portable support 103, the mating latching feature 203 of the retention member 211 latches a lip 218 or other surface or feature formed in the receiving member 207.

The casing 225 of the receiving member 207 is an external portion of the receiving member 207, providing attachment to frame 102 and providing structural support for the support cone 223. In one embodiment, the casing 225 is of a cuboid geometry. However, the casing 225 could be in the geometry of a cube, other hexahedron, or any other geometry with a top surface that is flat and at least one side surface that is flat. Having additional flat surfaces is preferred because the casing 225 can then be placed under the corner of a platform system 101 or under any other part of the platform system 101. A collar 237 is attached to the casing 225 with fasteners or by other methods and provides alignment of engaging structures and protects the components within and on the receiving member 207. Further, although not shown, collar 237 may be fitted with a cap or other structure to conceal the internal components, such as the support cone 223, of the receiving member 207 in the event that it is not desired to include structure on the upper side of the receiving member. The configuration of casing 225 allows for easier assembly of the platform system 101 because the receiving members 207 can be treated as interchangeable and a plurality of frames 102 having receiving members 207 may be brought together. Another aspect of an embodiment includes having at least one magnetic panel 227 on the side surface of the casing 225. The magnetic panel 227 allows for metal plates to be magnetically attached to the casing 225. Otherwise, the plates are attached with adhesives or hardware. In the platform system 101 the metal plates attached to multiple casings 225 provide a front surface for the stage, preventing people from walking underneath the platform system 101 and providing aesthetic benefits. In one embodiment, two flat side surfaces on the casing have magnetic panels 607. The arrangement allows for the receiving member 207 to be placed under the corner of the platform system 101 or any other part of the platform system 101, allowing for easier assembly of the platform system 101 because the receiving members 207 can be treated as interchangeable.

In one embodiment, the footing structure 104 on the portable support 103 may include a frusto-conical geometry or similar geometry. Tapered, frusto-conical, and conical geometry of the footing structure 104 on the portable support can allow the portable support 103 to stand without additional support. This allows additional portable supports 103 to be positioned on a platform or stage. Once the portable supports 103 are all positioned and engaged, a second platform or stage may be positioned and engaged at the distal end of the receiving member 207 of the portable support 103. The second stage or platform forms the second level for a multilevel platform system 101. The process may be repeated horizontally and/or vertically to produce a larger platform or stage on multiple levels. Tapered, frusto-conical, and conical geometry of the primary support structure 205 distribute the lateral forces allowing the platform system 101 to maintain stability, without swaying or bending, even when there are lateral forces present. In addition, the tapered, frusto-conical, and conical geometry help prevent misalignment of the portable support 103 by providing an engagement surface, the support cone 223, that aligns itself and allows people having little or no technical skill to assemble the multilevel platform systems 101 quickly and easily. Disassembly is also easily achieved by reversing this process.

The secondary support structure 107 (see FIGS. 2 and 12) is attached circumferentially to the support member 201. In an embodiment, the secondary support structure 107 is positioned at or near the end of the portable support 103 opposite the receiving member 207. The secondary support structure 107 can be positioned anywhere on the support member 201. Positioning the secondary support structure 107 at or near the end of the portable support 103 opposite the receiving member 207 may provide increased stability. One embodiment of the secondary support structure 107 includes a hook member 221 (see FIG. 12). The hook member 221 allows for at least one secondary support 105 to be attached to the portable support 103, allowing increased stability for the platform system.

FIG. 4 shows an embodiment of the portable support 103. The locking mechanism 203 comprises the retention device 211, an optional flange 215, the tapered portion 229, and the alignment member 213. The alignment member 213 comprises at least one channel 217. The at least one channel 217 can be configured to position the orientation of the locking mechanism 203 and, therefore, the portable support 103 (shown in FIG. 1). To position the orientation of the locking mechanism 203, the channel 217 is lined up with the pin 219 (not shown in FIG. 4) within the receiving member 207 (not shown in FIG. 4). In this embodiment, the attachment portion 231 is within the releasing mechanism 209 inside the support member 201.

FIG. 5 shows a cross-sectional view of a portable support 103 in engagement with a receiving member 207. As shown in FIG. 5, the tapered portion 229 is in engagement with an inner surface 501 of support cone 223. The inner surface 501 of support cone 223 preferably includes an angle configured to receive the tapered portion 229. The angle of inner surface 501 is configured to provide a surface that engaged the portable support 103 and resists lateral movement or flexing. In addition, the embodiment shown in FIG. 5 includes a footing structure 104 connected to a railing 117. Although the embodiment shown includes a railing 117, the footing structure 104 may be attached to stairs 115, or other structures having a footing structure 104 and an angled inner surface 504 and may be engaged with an outer surface 503 of support cone 223 of receiving member 207 (see e.g., FIG. 3). The outer surface 503 is configured with an angle that provides sufficient engagement and retention of the footing structure 104 that the railing 117 or portable support 103 is substantially prevented from twisting or wrenching out. That is, the engagement of footing structure 104, as coupling member 301 is sufficient to permit unsupported placement of portable supports 103 into receiving members 207 having lengths of 8 feet or greater, while retaining a substantially perpendicular positioning and resisting tipping or falling over. Such unsupported placement preferably permits the placement of a plurality of portable supports 103 prior to providing an additional level of frames 102 and panels 109, wherein additional levels can be lifted onto the unsupported portable supports 103 with one or only a few personnel.

FIG. 6 shows substantially the same arrangement as shown and described with respect to FIG. 4. However, in the embodiment shown in FIG. 6, the tapered portion 229 includes a first taper 601 and a barrel portion 603. The arrangement of portable support 103 in this embodiment permits the inclusion of addition devices or supports to be engaged with the tapered portion 229.
